While preserving and always displaying the donor institutions' verbatim data as we received it, we synonymized the thousands of scientific names received from contributing institutions to current taxonomic standards and added standardized common names. This, together with the project's extensive normalization and editing of all fields (dates, localities, place names, collector's names, etc.), georeferencing (applying latitude/longitude) with estimates of error, and addition of many categorical geographic fields (e.g., counties, drainage basins, Hydrologic Unit Codes, Natural Native Fish Conservation Areas, etc.), as well as thorough documentation of the complete data processing methodology, result in a very high quality data resource.

The online database includes occurrence records, as well as (for many records) collectors' original field notes, many specimen photographs, images of ancillary documentation (e.g., original jar labels), a large collection of images of both preserved and live specimens, beautiful full color illustrations of many species, and identification keys. Also available are species accounts for most species that summarize current knowledge of biology and ecology as gleaned from the literature. Online documentation for all aspects of the project is available, and the web site website allows users to upload comments and images linked to any record or locality. We encourage anyone interested in the Texas freshwater fishes to help us improve this resource by commenting and uploading their own materials to the website.
